GPT 6 Sol25.3/100

GPT 6 Sol: Newton's Mirror SVG benchmark
Researcher observations

The centered sphere, separate airborne black form and color ordering support scene recognition. Rounded shading and curved rims provide readable volume and gloss. Shrinking side images, a floor counterpart and curved lamp highlights provide isolated reflection cues, but broad bands and sparse repetitions leave nested room imagery, outer chains and ordered emitter mapping unsupported. Vertical framing departs from the prescribed view, while paint contact, transport and solid-metal appearance remain weak or uncertain.

Grok 4.732.8/100

Grok 4.7: Newton's Mirror SVG benchmark
Researcher observations

Some sphere reflections are correctly placed, with useful size progression and a floor image. Their overlapping side continuations and inverted floor paint order provide additional local optical cues. The gross paint sequence is recognizable, although crimson is a little too low. Incorrect lamp projections and absent nested and receding imagery still leave the mirror system largely incomplete.

Selfie

Different prompts

GPT 6 Sol65.8/100

GPT 6 Sol: Selfie SVG benchmark
Researcher observations

Six evenly spaced lobes, small outward-facing heads and a regular hexagonal opening make the motif immediately readable. The central angular band merges several intersections, weakening the alternating weave. Pale shading gives modest volume, but scales are sparse and repetitive, crossing shadows are weak, and the heads have limited anatomical definition.

Grok 4.768.8/100

Grok 4.7: Selfie SVG benchmark
Researcher observations

The bold spiral dominates an appealing, restrained silhouette, with crisp angular turns and subtle charcoal highlights. However, a visible background gap separates the shell from the body, making the shell appear suspended. The connected head and delicate eye stalks read clearly, while shading and small features remain simple.

Beach

Same prompt

GPT 6 Sol76.0/100

GPT 6 Sol: Beach SVG benchmark
Researcher observations

A cohesive, appealing beach illustration with framing palms, a warm sunset and a clear reflection path. The turtle, crab, birds and beach ball fulfill the playful brief. Clean silhouettes and restrained colors work well, while simplified anatomy, shallow spatial cues and inconsistent foreground shadows limit depth and finish.

Grok 4.762.3/100

Grok 4.7: Beach SVG benchmark
Researcher observations

The warm sunset, blue water and scattered beach activities create a cheerful, readable composition. Animals and equipment use basic silhouettes, with limited anatomical detail and grounding. The sun reflection forms a rigid tapered strip, and foreground objects lack cast shadows. Clean shapes support the illustration, but depth, materials and drawing complexity remain modest.

Mona Lisa

Same prompt

GPT 6 Sol53.5/100

GPT 6 Sol: Mona Lisa SVG benchmark
Researcher observations

The dark clothing, crossed arms, restrained smile and distant landscape establish the Mona Lisa reference. Replication is limited by the oversized, nearly frontal head, schematic eyes and fingerless hand shapes. Soft shading suggests facial volume, but muddy transitions and angular scenery weaken depth and painterly finish.

Grok 4.749.5/100

Grok 4.7: Mona Lisa SVG benchmark
Researcher observations

The dark clothing, crossed hands, restrained smile and muted landscape make the reference recognizable. Replication is limited by the oversized, simplified face, elongated neck and rounded hands with poorly resolved fingers. Gentle facial shading adds volume, but the clothing and landscape remain flat. Angular veil overlaps and a hard horizontal background boundary weaken the finish.

Raccoon

Same prompt

GPT 6 Sol78.0/100

GPT 6 Sol: Raccoon SVG benchmark
Researcher observations

The raccoon rides the dog's back, and the dog's connected foreleg reaches the steering grip. Expressive faces, a cohesive palette and sweeping wake make an appealing illustration. Vehicle construction and seating remain simplified; broad splash ribbons convey speed more convincingly than physical displacement. The sun has little corresponding reflection or effect on the subjects.

Grok 4.762.0/100

Grok 4.7: Raccoon SVG benchmark
Researcher observations

The raccoon rides clearly on the dog's back, and expressive faces, bright colors and a readable orange hull create a playful composition. Steering is unresolved: the dog's visible paws rest on the deck rather than grasping the controls. Simple body shapes and ribbonlike wake limit construction and movement. The glowing sun produces little corresponding illumination or reflection.

Pelican

Outside General and Visual Intelligence.

GPT 6 Sol80.3/100

GPT 6 Sol: Pelican SVG benchmark
Researcher observations

The pelican reads clearly, with an expressive face, generous bill and appealing pastel composition. Spokes, basket weave and feather contours are carefully organized. Both legs connect to the body, though joint definition and pedal contacts are simplified. Consistent wheel placement and a ground shadow establish support; restrained shading gives limited volume.

Grok 4.763.3/100

Grok 4.7: Pelican SVG benchmark
Researcher observations

The pelican reads clearly through its long bill, throat pouch and curved neck. Clean pastel shapes and balanced scenery make an appealing illustration. The riding mechanism is less convincing: feet lack clear pedal contact, steering is unresolved, and the frame lacks a coherent drivetrain. Simple shading and sparse feather detail limit depth and finish.
